MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 354,074, dated December7, 1886.

Application led August 10, 1886. Serial No.210,5'13. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JAMES S. SWAN, a citizen of the United States,residing at Mongaup Valley, in the county of Sullivan and State of NewYork, have invented certain new and useful Improvements in MechanicalMovements; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which Yit appertains to make and use thesarne, reference beinghad to the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specilication.

Figure l of the drawings is a representation of an elevation of one sideof niy invention. Fig. 2 is a view taken from the opposite side, partlybroken away. Fig. 3 is a transverse section on line x x. Fig. l, andFig. iis a simi lar section on the line y y, Fig. l.

My invention relates to mechanical movements for operating any lightmachinerysuch, for instance, as stone-Crushers, grindstones, orcoffee-mills; and it consists in the construction and novel combinationof parts, as hereinafter described, and pointed out in the claim. y

Referring by letter to the accompanying drawings, A designates the frameof the machine, having its side beams, B C, slotted longitudinally at DE ou parallel lines. The frame A is provided beneath the side beams, BC, with parallel rack-bars F G, said rackbars being provided in thefront portions of their upper edges with teeth H. rIhe rear portions ofthe rack-bar F G are provided with longitudinal slots K L, which areopposite and parallel to each other.

rl`he side beam, B, is provided at its front end with a power-wheel, M,which is connected by a pitman-rod, N, to the shaft P of adoublesegmental rocking-gear, Q. the teeth of which engage the teeth H oftheraclrbars F G, said teeth H being in the upper edges of the front.

`arm T to guide it in its reciprocal movements.`

The cross-arm T is connected by a rod, W, with a steam-engine or othermotor, so that power may be communicated frein the same to themechanical movement.

In attaching my improvements to any of the above-named machines it isonly necessary to place the pulley-band over the power-wheel M; or theshaft of' this wheel might be extended and provided with a crank-arm tobe connected with the drive-wheel of the machine to he operated.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

The combination, with the frame composed of the slotted parallel sidebeams and the slotted rack-hars, of the power-wheeljournaled on anextension of the frame and connected to the shaft of the doublesegmental gear by a pitman-rod, the strap-arms connecting the segmentalgear with the pitman-rod T, and the cross arm working in the slottedrack-bars, substantially as specitied.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES S. SVAN.
